On the inner display
iPhone Duo shows each app in one of three ways depending on which SDK it was built with: letterboxed with black bars (iOS 26 or earlier), expanded with some empty space (iOS 27), or full screen (iOS 27.1 and later). We don't yet know which applies here.
U校园AI版 has no iPad version today, so its layout has only ever been designed for phone-sized screens. That doesn't mean it won't adapt — only that its developer is starting from a phone layout rather than an iPad one.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including U校园AI版. Open it on the inner display, then add a second app next to it. You can save the pair and come back to it later.
Duo-specific features
None confirmed yet. Duo-specific features include side toolbars, layouts that react to the fold, and content on the outer display while the app is open inside.
Evidence & history
No public evidence yet. iPhone Duo ships on October 23, 2026; if you have one, tell us how U校园AI版 looks — a screenshot helps.

Questions
Does U校园AI版 work on iPhone Duo?
Not confirmed yet. U校园AI版 runs normally on iPhone Duo's outer display, but there's no reliable report yet of how it looks on the inner display.
Does U校园AI版 work on the outer display?
Yes. iPhone Duo's 5.4-inch outer display behaves like a regular iPhone screen, so every iPhone app works there as usual.
Can I use U校园AI版 in Split View on iPhone Duo?
Yes. On iPhone Duo every app can be placed side by side with another app on the inner display — developers don't need to opt in. How comfortable it feels at half width depends on the app's layout.
Will U校园AI版 have black bars on iPhone Duo?
It depends on the version of Apple's SDK the current build of U校园AI版 uses: iOS 26 or earlier means black bars, iOS 27 means mostly filled, iOS 27.1 means full screen. We'll update this page as soon as there's evidence.
